When you register your PLB, make sure you give emergency contracts who will know where you are, in the case of an emergency when you need to activate your PLB. This aids the rescue authorities to make sure it is a real alert and will speed up your rescue.
If I register my PLB1 in one country, can I use it in another country?
Yes. You can use your PLB1 anywhere in the world.
When I register my PLB1, is the 0 in the 15 digits HEX ID (UIN) the number 0 or the letter O?
The HEX ID consists of the number from 0 to 9 and the letters from A to F only. Therefore character 0 is the number 0.
